A coil with an unknown resistance and inductance


A coil with an unknown resistance and inductance isconnected in series with a resistor of 12 ohms and a capacitor of168 micro farads. The circuit is connected across a 220V 50Hzsupply, with lagging power factor of 0.7145. Measuring the voltagedrop across the resistor yields a 135V reading. Calculate :
a) Voltage drop across the capacitor and the coil.
b) The resistance and inductance of the coil.
c) The Power dissipated in the whole circuit.
